Chapter 7 Community Structure
Next, we calculate the communities in each network using the Spin Glass algorithm. Although there is no widely accepted definition of communities (Baroncelli, 2012), communities are generally considered to be nodes that are more connected to each other than to other nodes. For demonstrative purposes, we separately collapse across the 20s and 60s and run the networks. Then we calculate their community structure and compare them. ## Multi-Trait ### Run Communities
